           Summary: wkSetUpFontCache() may be called before the SPIs are
                    connected.
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: webkit-bugs at gentlyusedunderwear.com


If a menu (such as the bookmarks menu) is opened before a WebViewFrame is
created, then wkSetUpFontCache will be a NULL pointer. As the menu rendering
calls +[WebStringTruncator centerTruncateString:toWidth:] which then calls
+[WebTextRendererFactory sharedFactory] the wkSetUpFontCache pointer won't have
a chance to be "connected" and thus will cause a crash.
